Is there an app on the App World that has a timer that you can set and when the time is reached, the app will automatically turn off the Playbook?

I would love to see this app or feature on the Playbook to save some juice.

No such app exists nor is it possible for a 3rd-party developer to write one. Perhaps someday RIM will provide some APIs that will allow this level of control.

Until such kind of APP is available, you can try this > get your mobile... set an alarm to your mobile... when that alarm goes off, get up... get your PlayBook... and turn it off...

Such an app will never be available. It's a security exploit.
